7904885 ÷ 436 
The aim is to understand the frequency of 436 in 7904885.

Let's proceed to step 1:
436 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 436

Moving on to step 2:
The number 436 fits into 79 0 times, leaving a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Include the next digit (0) from the dividend after 79, then repeat: 790 / 436

Step 3:
If we divide 790 by 436, we get 1 and a remainder of 354.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 436 away from 790, we end up with 354.
Fetch the next digit (4) from the dividend, attach it to 354 and continue: 3544 / 436

On to step 4:
The number 436 fits into 3544 8 times, leaving a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 3488 from 3544 leaves us with 56.
Take the next digit (8) from the dividend and append it to 56, then repeat: 568 / 436

Advancing to step 5:
If we divide 568 by 436, we get 1 and a remainder of 132.
The next digit of our result is 1. 
Result so far: 181.0
Subtract 436 from 568 to get 132.
Grab the next digit (8) from the dividend, add it to 132, then carry on: 1328 / 436

Advancing to step 6:
When dividing 1328 by 436, we get 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 1813.0
Subtracting 1308 from 1328 leaves us with 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 436

Step 7:
When dividing 205 by 436, we get 0 with a remainder of 205.
Use 0 as the next digit of our solution. 
Result so far: 18130.0
If we take 0 away from 205, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 8:
2050 divided by 436 is 4 with a remainder of 306.
Write down 4 as next digit of the result. 
Result so far: 18130.4
The remainder is 306 after subtracting 1744 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 9:
The number 436 fits into 3060 7 times, leaving a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 18130.47
Deduct 3052 from 3060 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
436 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 18130.47
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
When dividing 800 by 436, we get 1 with a remainder of 364.
Write down 1 as next digit of the result. 
Result so far: 18130.4701
If we take 436 away from 800, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 12:
436 can be fit into 3640 8 times, resulting in a remainder of 152.
Record the quotient 8 as the next digit in the result. 
Result so far: 18130.47018
Deduct 3488 from 3640 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 13:
If we divide 1520 by 436, we get 3 and a remainder of 212.
The next digit of our result is 3. 
Result so far: 18130.470183
Subtracting 1308 from 1520 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 14:
The number 436 fits into 2120 4 times, leaving a remainder of 376.
Record the quotient 4 as the next digit in the result. 
Result so far: 18130.4701834
Deduct 1744 from 2120 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 15:
436 goes into 3760 8 times with a remainder of 272.
The number 8 becomes the next digit in our result. 
Result so far: 18130.47018348
Subtract 3488 from 3760 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

In conclusion, the division gives 18130.47018348 with a balance of 2.72e-07.
